dc.description.abstractThis paper presents and analyzes the behaviour of TRIP 1000 steel sheets subjected to low velocity perforation by conical projectiles. The relevance of this material resides in the potential transformation of retained austenite to martensite during impact loading. This process leads to an increase in strength and ductility of the material. However, this transformation takes place only under certain loading conditions strongly dependent on the initial temperature and deformation rate. In order to study the material behaviour under impact loading, perforation tests have been performed using a drop weight tower. Experiments were carried out at two different initial temperatures T0 213 K and T0 288 K, and within the range of impact velocities 2.5 m/s 6 V0 6 4.5 m/s. The experimental setup enabled the measuring of impact velocity, residual velocity, load time history and failure mode. In addition, dry and lubricated contacts between the striker and the plate have been investigated. Finally, by using X ray diffraction it has been shown that no martensitic transformation takes place during the perforation process. The causes involving the none appearance of martensite are examined.
